Improved extraction method for the determination of iron

A simple and fast procedure is proposed for the extraction of iron (Fe), copper (Cu), and nickel (Ni) in 16 varieties of sunflower seed oil samples using an ultrasonic bath. The experimental parameters of the ultrasonic-assisted extraction (UAE) method were optimized to improve the sensitivity and detect the metals at trace levels in minimum time.

The extraction of copper and iron with Lix 64N and

Oct 01, 1975· The extraction of iron and copper with Lix 64N and mixtures of Lix 64 N and Versatic 911 in kerosene. Log D vs pH relationships for the extraction of Fe (III) with Lix 64N are shown in Table 2. For the extractant concentra- tions from 5.0-25% the average slope of the correspond- ing lines was 2.9, in agreement with Eqn (1).

EXTRACTION OF COPPER

COPPER AND THEIR EFFECTS Blister copper is 99% pure. It contains impurities mainly iron but little amount of As, Zn, Pb, Ag and Au may also be present. These impurities adversely affect the electrical as well as mechanical properties of copper. Therefore, they must be removed. REFINING OF COPPER Blister copper is refined by electrolysis.

Influence of indigenous and added iron on copper

Oct 15, 2009· In both the figures, also the amount of Ca extracted at each step is shown. The presence of added iron determined a lower copper extraction at the end of each test, and the extent of copper extraction yield reduction was higher when the excess of EDTA in the leaching solution was higher.

Extraction of iron from copper-plant slag SpringerLink

Jan 05, 2017· In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification products of carbon in
